i have an obd1 jdm swapped gsr and after i put in a bored out ported and polished throttle body it started bogging down sometimes then sometimes its good. i have a crack in my header and put jb weld on it and after i took tht off accidentally its been doing it, i put some more on it and it still does it. also when it bogs down it shows nothing on my air fuel ratio guage, could it be fuel filter, o2 sensor, fuel pump?? im not sure, any help would b great

 

MAP maybe. Bad O2 can cause numerous problems as well. More likely the O2. There is a way to test. Unhook the O2, if it runs better unhooked it is the sensor, if it runs worse when disconnected, then it may be ok but another problem it could be.

 

yea i got a dif. map with the throttle body but i lost it or id try tht

 

get it tuned!

 

yea it mite make a difference, the ecu is already chipped with hondata s100 with a 5200 vtec and no revlimiter

 

yea i put the different map on it, and after i drove it a little bit it still bogged but once the temperature dropped it ran perfectly

 

but it runs like total **** wen its hot out, it drops down and almost cuts off. any help?

 

Check the TPS on the TB. Or change back to the old TB and see if you have any problems.

 

wat volt is the tps suposed to read?

 

if i remember right its .5 at closed and 4.5 at Wide open
